Summary

This study aims to identify non-genetic factors that cause only one twin in a pair to get breast cancer. This information could help researchers identify ways to help prevent breast cancer from occurring.

What does participation involve?

If you agree to participate in the “Study of Breast Cancer in Twin Pairs”, you will be asked to do the following:

• Complete an online questionnaire about your childhood, your early development, and your lifestyle (and cancer, if relevant).

• Provide a sample of saliva, which will contain cells from which your genetic code can be studied. You will receive a kit in the mail and mail it back to the research team at no cost to you.

• If you have been diagnosed with breast cancer, you will be asked to sign a form to give the research team your permission to obtain a Pathology Report from your physician or surgeon, and if available, a sample of the cancer tissue. These materials will allow the research team to obtain a detailed description about your cancer.

This research requires detailed comparisons between the members of twin pairs. Therefore, the research team may also ask that you put them in touch with your twin to see if she is interested in participating in this study with you.
